Today we will look at the monitor EliteDisplay S231d from HP from the year 2014. Within this article, we will first take a closer look at the most important feature of a monitor -the display-, then the design, and in the next section we will go into the features of the monitor. Of course, power consumption, certifications, connectivity and other important details will also be considered.
Display
23 inches ( 58.4 cm on the diagonal) offer sufficient space for texts in any office applications, for example. While classic CRT monitors were built with a screen ratio of 4:3, this monitor has a ratio of 1.778 : 1 (width to height). Approximately 81.4 % of the front surface of the monitor is taken up by the display, while the remaining part is screen edges that do not allow the image to be displayed. If you want to place several monitors next to each other, it is advisable to choose models with narrow edges. The display is a IPS panel. The panel has a resolution of 1920 x 1080 px. The pixel density is 95 ppi. The pixel pitch is 0.265 mm. The continuous possible brightness specified by the manufacturer HP is 250 nt. The panel is illuminated by W-LED. The built-in panel ensures stable color reproduction of the image, even at deviating viewing angles, by means of its 178 ° (horizontal) viewing angle. HP promises stable color reproduction moreover within a 178 ° vertical angle. The refresh rate is horizontally seen at the EliteDisplay S231d 24 khz to 80 khz. Vertically, however, the image renews at a minimum rate of 50 hz up to 60 hz. The minimum response time of the monitor is ms. The display panel is Anti-glare/Matte.
Color space
The panel has a bit depth of 8 per color channel, but what does that mean? The number of bits determines how many colors can be encoded for the individual pixels of the display. For an 8-bit panel, for example, this is 256 different colors (2^8 = 256). However, since we usually display three different colors per pixel at the same time, in theory about 16 million (256^3) different colors are possible by mixing the three pixels. A 10-bit panel could even display a billion colors. According to the manufacturer, the coverage of the NTSC 1953 color space is 72 %.
Contrast ratio
Contrast ratio is a common measurement used to represent the maximum relative differences in brightness between black and white. It describes the ability of a screen or projector to produce a high-contrast image and is the quotient of the maximum and minimum displayable luminance. The higher the values are away from each other, the stronger the quantitatively seen difference between black and white is set up, which in turn results in an improved image quality. This monitor from HP has a static contrast ratio of 1000 : 1 , according to the manufacturer. In contrast to the static contrast ratio, the dynamic contrast ratio changes the brightness of the panel itself in addition to the difference measurement from black to white. In addition to the difference between the brightest and the darkest pixel, the backlight is thus changed. Since the brightness of the panel may not be able to be adjusted exactly to a single pixel, a so-called halo effect is possible. The value of 5000000 : 1 of dynamic contrast ratio for the monitor EliteDisplay S231d cannot provide any information about the severity of the halo effect here. Therefore, it is more useful to compare the static contrast ratio.
HDR
The monitor supports all HDR modes listed here:
screen design
Without the stand, the monitor comes with a width of 54.4 cm , a height of 32.9 cm and about 5.1 cm.
If you want to place the monitor described here on the desk without a wall mount, you should allow for 46.9 x 54.4 x 24.2 cm (HxWxD) of space. The device weighs in total (i.e. also measured with the stand) 6.12 kg. Without stand, the monitor weighs 3.87 kg. Speaking of weight without a stand and thus wall or table mounts. The monitor supports a Vesa mounting. A height-adjustable stand ensures an improved ergonomic posture during use. The monitor can be moved to a maximum height of 15 cm. This value is always measured from the bottom edge of the screen.
Rotate, tilt and swivel
The monitor from HP has a pivot function and can thus be rotated using the included stand. A rotation to the left is possible with up to 0 degree. To the right, the monitor can be rotated by 90 degree. The EliteDisplay S231d can be swiveled when mounted on the included stand. Pivoting to the left is possible up to 180 degree. Pivoting to the right is possible up to 180 degree. Thanks to the tilt function of the EliteDisplay S231d monitor, the screen position can be flexibly adjusted to minimize dazzling light sources and ensure optimum visibility. The angle of inclination to the rear is 30. The monitor can be tilted forward by 5 degree.
Ports
The monitor can be connected via 1 VGA ports. With the built-in 1 RJ45 Ethernet port(s) on the ' EliteDisplay S231d ' monitor, users can establish a wired network connection. This feature provides a stable connectivity option for those who need a reliable network connection, whether for professional tasks or mission-critical applications.
camera
With fewer cables on the desk and additional features, the EliteDisplay S231d impresses with a built-in webcam, which can be used for online meetings, for example. The built-in camera has a maximum resolution of 1280 x 720 px when recording video with the camera.

Features
- The display/monitor supports Frame Rate Compensation.
WiFi / Bluetooth
Power consumption
The average consumption figure for EliteDisplay S231d is 38 w. The maximum power consumption (peak) specified for this monitor is 60 w. In standby mode, the device consumes approximately 2.2 w. When switched off, on the other hand, the monitor consumes only 0.5 w. In ECO mode, the monitor consumes 19.37 w. The monitor can be operated on a 110v power supply. The monitor can be operated on a 220v power supply. The power grid has to supply a frequency of 50 hz to 60 hz.
Environment
The maximum height at which the monitor may be operated, according to the manufacturer's specifications, is 5 km. During operation, the ambient temperature must not exceed 35 °C , to ensure full functionality. Below a temperature of 5 °C , the monitor from HP should again not be used. The humidity must not exceed 80 percent. At least, however, 20 percent humidity. The monitor may be stored at a maximum humidity of 95 percent. The minimum humidity during storage should not fall below 5 percent. The maximum storage temperature should be according to HP 60 °C. Minimal were given by HP -20 °C. According to the manufacturer, the monitor may be stored at a maximum height of 12.192 km.
